How to grow Sauromatum giganteum in the UK

Sauromatum giganteum, commonly known as the voodoo lily or giant voodoo lily, is an unusual and fascinating plant known for its large, exotic-looking leaves and unique bloom. It can be grown in the UK, but it requires specific care due to its native tropical and subtropical habitat. Here’s how to grow Sauromatum giganteum in the UK:

1. Choose a Suitable Location:

• Select a planting location that receives dappled or indirect sunlight. Avoid direct sun exposure, especially during the hottest part of the day.

2. Soil Preparation:

• Voodoo lilies prefer well-draining, rich, and organic soil. You can amend your garden soil with organic matter like compost to improve its fertility and drainage.

3. Planting:

• Plant the tuber-like corms of Sauromatum giganteum in early spring after the last frost date. Plant them about 4-6 inches deep and spaced 12-18 inches apart.

4. Watering:

• Keep the soil consistently moist during the growing season (spring and early summer). Water when the top inch of soil feels dry to the touch. Reduce watering in late summer when the plant goes dormant.

5. Fertilization:

• Fertilize your voodoo lily sparingly with a balanced, slow-release fertilizer in early spring when new growth starts. Avoid over-fertilizing, as excessive nutrients can harm the plant.

6. Mulching:

• Apply a layer of mulch around the base of the plant to help retain moisture and regulate soil temperature. This is especially important during the colder months.

7. Protect from Frost:

• Voodoo lilies are frost hardy to a certain degree but must be kept reasonably dry. If they are wet over winter then the bulbs will rot. (If you are going to leave them out and take a chance it is best to cover in a thick mulch) In the UK, it’s important to protect them from frost during the winter as our winters tend to be wet. Before the first frost, dig up the corms and store them in a cool, dry place for the winter, ideally at temperatures around 50-60°F (10-15°C). Replant them in spring.

8. Maintenance:

• As the plant grows, it will produce large, tropical-looking leaves. Prune any damaged or yellowing leaves to maintain the plant’s appearance.

9. Blooming and Dormancy:

• Sauromatum giganteum has a fascinating bloom that resembles a corpse flower. The inflorescence appears in late spring to early summer.
• After flowering, the plant will start to go dormant, and the leaves will die back. This is a natural part of its growth cycle. Reduce watering during this period.

10. Pests and Diseases:

• Keep an eye out for slugs and snails, as they can damage the foliage. You can use organic slug and snail control methods to protect your plant.

By following these guidelines, you can successfully grow Sauromatum giganteum in the UK. Remember to provide protection from frost during the winter months to ensure the longevity of your voodoo lily.
